Correct answer & explanation
✓
User enters command on device
TACACS+ command authorization starts with the user entering a command, which is sent to the TACACS+ server. The server checks the command against the user's authorization profile and responds with permit or deny. The device executes or blocks the command accordingly, and finally logs the result.

AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
